COTTON-SEED-DELINT'ING MACHiNE.

SPECIFICATION forming part of Letters Patent lfl'o. 597,125, dated January 11, 1898.

Application-filed. August 9 1895.

To aZZ whom it may concern.-

Be it known that I, FRANK E. ROSAMOND, a

citizen of the United States, residing at Memphis, county of Shelby, and State of Tennessee, have invented certain new and useful Improvements in Cotton-Seed-Delinting Ma-. chines, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

My invention relates to the construction of the clothing or external covering for the abrading-cylinder in a cotton-seed-delinting machine.

The invention, generally stated, consists in an abrading or scouring block having a flanged or broadened base on which is formed an abrading projection and in a delintingcylinder provided with a multiplicity of such blocks. Such block is curved to fit the cylinder-surface, its flanged or broadened base providing means for attaching it to the cylinder, and aplurality of such blocks are adapted to entirely cover the surface of the cylinder, so as to present a continuous abrading or scouring surface. Preferably such blocks are cast out of emery or similar material in the plastic state and baked tovhardcn them.

In illustration of this invention I have shown in Figure 1 a plan view of a portion of a debuting-cylinder of a cottonseed-delinting machine, one of the blocks being removed to show the relation of the blocks to each other, and in Fig. 2 an enlarged perspective View of the block so removed.

In order to provide an abrading or scouring surface, consisting of emery or corundum, which will be effective in performing such a scouring or abrading action upon cotton-seed as will detach the adhering lint therefrom without injury to the seed, it is desirable for perfect work that it shall not only consist of numerous blocks or projections cast out of emery, so as to provide the cylinder with an undulating surface, butthat the whole exposed surface of the debuting-cylinder carrying the blocks shall be emery-clad, so that contact with any part of its surface will produce a scouring or abrading action upon the seed. To attain these ends, the cast emery blocks not only require to have their bottoms Serial No. 558,798. (No model.)

or supporting-surfaces curved to lit the exterior of the cylinder, but these blocks must be separated from each other considerably in order to successfully operate upon cotton seed and detach the fibers or lint therefrom. Such cast emery blocks so disposed upon the cylinder present difficulties in securely attaching them to the cylinder, so that they will not break, be loosened from, or become disturbed in their proper relation to the cylinder by the centrifugal action to which they are subjected in the delinting operation. In or der to construct these blocks so that they may be attached securely in place upon the debuting-cylinder C and at the same time provide the surface of said cylinder with a continuous clothing of abrading material, I cast the blocks B out of emery in the plastic state and provide their protruding bodies or abradin g projections with broadened bases or laterally-projecting flanges 6, so shaped that the blocks when laid onto the cylinder, either staggered or ranged side by side, may have fastening-screws 3 passed through said flanges at many points, as through the'holes 2, and thus provide them with means strongly securing them to the cylinder, preferably at two or more points.

The general form of the flanges 6 is preferably rectangular, and the bottoms of the blocks which lie next to the surface of the cylinder are curved to correspond with the arc of said cylinder, so that a number of said blocks placed side by side and end to end upon the cylinder and secured thereto will so cover its face or exterior surfaceas to provide the same with a continuous cast emery or abrading surface made with circumferential and lateral channels, thus forming longitudinal and transverse passages between the blocks for the passage of the seed.

By constructing the blocks with projecting flanges, adapting contiguous blocks to snugly fit each other, mutual support against endwise or sidewise movement will be provided, while the flanges provide a means of attaching the blocks to the cylinder, the holdingbearing of which fastening means is so near the surface of the cylinder as to provide a securement that has great resisting power exerted against the tendency of the centrifugal action to force the blocks off, and thus the blocks are so strongly sustained as to resist all tendency to detachment. This structure of block also provides a ready means for detaching a defective block and replacing the same by a perfect substitute.

\Vhat I claim is- 1. An abrading-block consisting of a broadened base on which is formed an abrading projection, substantially as described.

2. A cast emery abrading-block consisting of a broadened base on which is formed an abradin g projection, substantially as described. v

3. In a cotton-seed delinter, a delinting-cylinder provided with a multiplicity of east emery blocks Whose protruding bodies are provided with laterally-projecting flanges by which they are attached to the cylinder, and separated from each other, substantially as described.

4. In a cotton-seed delinter, a delinting-cylinder provided with cast emery blocks consisting of protruding bodies curved transversely and having rounded ends, and provided with laterally-proj ectin g flanges whereby longitudinal and transverse passages for the seed are providedbetw'een said bodies, substantially as described.

5. In a cotton-seed delinter, a delinting-cylinder provided with a multiplicity of cast emery blocks consisting of protruding bodies provided with laterally-projecting flanges at their bases through which passes the means for fastening said blocks to the cylinder, whereby the cylinder. is provided with acontinuous abrading-surface from which projects a multiplicity of abrading protuberances, substantially as described.

6. In a cotton-seed delinter, a delinting-cylinder provided with a multiplicity of cast emery blocks whose curved protruding bodies have rectangular bases consisting of laterallyprojecting fianges,whereby is provided means for fastening said blocks to the cylinder, and the cylinder is given a continuous but undulating abrading-surface, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
